I was wondering if you guys new what type of emissions regulations are required in the state of California? Can you straight pipe a turbo diesel and still be street legal or will it be an offroad only truck. Any help appreciated.

tecenicaly if you remove or tamper with the cat. it is ilegal to be on the public roads and would be a offroad olny truck........ but thats olny if you git caught and its generaly just a fixit tickit if thay bust you . most of the guys aroud hear runn strate piped catless truck and havent had any problems with the fuz.
